Question

In the system shown m a m_{a} m a ​ =4m, m b m_{b} m b ​ =3m and m c m_{c} m c ​ =8m. Surfaces are smooth and string is light/inextensible. On release, acceleration of block B is:

G1 Physics · Accepted Answer

Write Newton's laws for A,B and the outer frame C with the string constraint. Solving gives a b a_{b} a b ​ =g/2 leftward. Option B.
